Description Ecopladib (PLA 725) is a sub-micromolar inhibitor of cytosolic phospholipase A2α (cPLA2α), with IC50s of 0.15 μM and 0.11 μM in the GLU micelle and rat whole blood assays, respectively.
In vitro Ecopladib在20μM的浓度下对COX-1和COX-2均无活性,而这个浓度是其在MC-9细胞中IC50的近100倍。Ecopladib能够抑制通过12-lipoxygenase和15-lipoxygenase途径从花生四烯酸衍生的12-和15-HETE,其IC50约为0.3μM。在PAPE脂质体测定中,Ecopladib在37nM的浓度下对cPLA2α的抑制率为73%,而在1μM的浓度下对sPLA2的抑制率为16%。Ecopladib抑制前列腺素(PGF2α)及白三烯(LTB4和LTC4/D4/E4)的生成,这些化合物的IC50较为接近,约为20-30nM[1]。
In vivo 剂量-反应研究显示,口服 Ecopladib可降低卡拉胶诱导的爪肿胀,其ED50为40 mg/kg。在该模型中,Ecopladib展现出8 mg/kg的ED50,证明其能够在体内抑制COX-2衍生的PGE2形成[1]。
